I have recently put together my first gaming PC on a fresh harddrive and windows install. At random intervals between 5-20 min after starting my PC, my PC is either re-booting or showing the Blue Screen of Death with either of the following messages:

>KERNAL_SECURITY_CHECK_ERROR
>IRQL_NOT_LESS_OR_EQUAL

As it is a fresh build, it is most likely hardware related although I cannot see why. All my drivers are up to date, and and I have run diagnostics on my RAM with no results.
